There is one issue that I have with the phone, and I hope it starts getting a little more attention and I hope it can be addressed.
I have a phone now, and love it so far. Save for one problem: the camera.
I noticed on other people's iPhones (they are usually older/closer to launch models) that their camera is normal, while mine has a green hue to everything it takes. Apparently it is an issue with the white balance.
Closer inspection at an Apple store and I noticed that some of the phones they had out to demo also had the same problem, while others did not.
It's also mentioned here:

Obviously this can be corrected with photos taken off the phone, since you can correct them on your system with iPhoto for example. But it's just a little annoying to know that some people, who should have the same thing I do, don't have to deal with the hassle.
It also appears (just with talking to/looking at phones that people have just bought that I know) that a good majority of the 'newer' ones are doing the same thing.
